Molecular oxygen was excited by 1.5–3.0 keV electrons. Luminescence spectra from the decay products of K-shell excitation were obtained at high resolution (bandwidth of 0.3 Å). With this resolution it was possible to identify and assign the observed lines to transitions from highly-excited Rydberg states of O+ and O fragments. These states appear to result from inner valence two-hole states and three-hole, one-electron states produced by Auger decay of the core hole in molecular oxygen.

    The main luminescence bands in silica SiO2 are the red luminescence R (650 nm, 1.9 eV) of the non-bridging oxygen hole center, and the blue band B (460 nm, 2.7 eV) and ultraviolet luminescence UV (290 nm, 4.3 eV), both commonly related to oxygen-deficient centers. In the present work, we will...

    It is shown on the basis of an analysis of the J-band shape, luminescence spectra, and luminescence decay that self-trapping of excitons takes place in J-aggregates with strong topological disorder. A self-trapping barrier must be overcome for this to occur. A microscopic model of the...
